To all whom it may concern:

Be it known that I, Gnonon B. KEPLIN- can, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Marking and Shading Pens, of which the following is a specification.

' This invention relates to marking and shading pens and has as one of its objects to provide a pen of this class which will be adapted for the employment of ordinary writing fluid or heavier shading inks either separately or simultaneously, and which will be capable of being used for a considerable length of time without requiring to be refilled. Y

Another aim of the invention is to pro.- vide a pen of this class embodying a reservoir which is of transparent material enabling the user of the pen to readily ascertain at all times the quantity of inkcontained Within the said reservoir so that before applying the pen where a mark or figure of considerable length or extent in other directions is to be made, he may determine whether or not there is sufficient ink contained within the reservoir to enable him to actually complete the line or figure.

Another aim ofthe invention is toprovide a pen of this class embodying anink reservoir which pen will be so constructed that it may be laid down in any position without likelihood of the ink being spilled and may be in use, tilted to any angle without such loss of ink occurring.

In one embodiment of the invention the reservoir of the pen is divided into a numberof ink compartments each of which may contain an ink of a color different from that contained within any of the other compart- Inents so that by a single stroke of the pen a broad line or a series of lines comprising difierent colors may be drawn, thus enabling the figure or design to be executed in a more symmetrical manner than would be possible if each line of a different color were required to be separately drawn.

it is a further object of the invention to so form the marking edge in one embodiment of the invention that the colors from the several ink compartments or chambers may beblended. r In the accompanying drawings: a

Fig.8 is a detail vertical sectional view through the lower end of the filler tube.

Fig. 9 is a bottom end view'of the pen shown in Figs. 1 and 2 of the drawing.

In the drawings the reference numeral 1 indicates in general the reservoir of the pen and 2 a tubular socket which is carried by the back of the reservoir and receives one end of thestaff of the pen which is indicated by the numeral 3. As before stated, the reservoir is formed from transparent ma: terial and preferably from sheet celluloid of a suitable thickness, the material being molded upon hot dies to the required shape.

In all forms of the invention the reservoir ispreferably substantially of ovate-acuminate shape in cross section, the broader side of the reservoir constituting the back thereof and supporting the socket 2, and the apex or narrow end of the body constituting the marking edge. The front of the reservoir is indicated by the numeral 4 and the rear side thereof by the numeral 5, the end walls being indicated by the numeral 6 and being ooncavo convex with their convex sides presented outwardly, as clearly shown in Figs. 3, 4, 5 and 6 of the drawings. lhe front and rear walls 4 and 5 of the reservoir are preferably formed by molding a sheet of the material from which the reservoir is formed, upon a die of the proper shape so that the opposite edges of the sheet will be brought together in overlapped relation. A number of small wires are then disposed between the overlapped edges of the sheet and these edges are pressed together and subjected at the same-time to heat whereby they will. become united to each other. The wires are then withdrawn and as a result capillary ducts 7 are formed in the marking edge of the'reservoir and these ducts open at their '25 said chambers, the ink being independently lower ends at the said edge and at their up per ends communicatewith the interior of the reservoir. The reservoir may comprise a single chamber or compartment or it may be divided by one orv more partitions 8 into a number of ink chambers or compartments 9 and it will be understood that these partitions are preferably of the same material as the walls of the reservoir so that the quantity of ink contained in each chamber or compartment may be readily noted. In that form of the invention shown in Figs. 1 to 3 inclusive of the drawings, the marking edge of the device, which edge is indicated specifically by the numeral 10, is unbroken and asa consequence ink flowing through. V the capillary ducts 7 to the said edge will be distributed along the entire length of the I edge and the figure drawn will be in a solid color or colors. As before stated, the reservoir 1 may comprise a single chamber or a plurality of chambers and in the latter instance each chamber may be filled with an ink of a color different from that contained in the next adjacent or any other one of the fed fromthe respective chambers through I the capillary ducts and on to the surface "iii over'which the marking edge is passed. In order that the reservoir may beconveniently filled with ink,v thereservoir is provided in its front wall with a fillingopening 11 of small size andtapered and where the reser- 1 voir embodies a singleink chamber but a single one of these filling openings will be provided. However, where the reservoir comprises a number of ink chambers one of the openings will be provided for each chamber as will be readily understood. In a like manner the front wall 41 of the reservoir is provided with one or more ventopenings 12 located atthe top of said wall. lhe manner of fillingthe chamber or chambers of thereservoir will be presently more fully described. I

In that form. of the invention shown in I Fig. 4; Of the drawings, the marking edge intoa number of marking points indicated by the numeral 15. The capillary ducts in the marking edge of thepen in this form of of'thereservoir is indicated by the numeral X13" and thisedge isprovided at intervals with slits 14 extending a'short distance into the said edge portion and dividing the same theinvention may be so arranged that one severalof th ducts will extend through a single one of the points 15, it being understood that where, for example, two-capillary ducts 'extend through a single marking oint, as 'indicated at 16, a broader line will "edr'awn than where a single ductextends through a single one of the said points. It

7' ivvillfurther beunderstood-that in the use of '"a pen'of this form a plurality of lines will be drawn upon the surface over which the marking edge is moved and that the distance between the said lines will be uniform in all directions of movement of the pen over the said surface.

In that form of the invention shown in Fig. 6 of the drawings the ink ducts are in- 'dicated by the numeral 17 and instead of being capillary are relatively broad or more nearly in the nature of narrow slots so that where these duct 17 are formed in an unbroken marking edge the ink will be supplied more'r'eadily than in the case of the capillary ducts 7 and where the said ducts 17 are formed in separate marking points, lines of different widths may be drawn.

In order that the reservoir may be conveniently supplied with ink, a filling device such as shown in Figs. 7 and 8 is preferably employed and this device includes a tube 18 which is preferably of glass and which is provided at its upper end. with a rubber cap 19 resembling the cap of an ordinary medicine dropper or fountain pen filler. The lower end of the tube is contracted as indicated at 9.0 and has embedded in it a small tube 21 which projects beyond the end of the portion 20 and is of a diameter to fit within the filling opening 11 in the wall of the reservoir. After ink has been drawn into the tube 18 by compression and release of the bulb 19, the projecting end of the tube 21 is inserted intothe opening 11 in the wall. of the reservoir or chamber which it is desired to fill with ink and the bulb 19 is then compressed so asto discharge the ink from the tube 18 into the said reservoir or chamber, air escaping from the reservoir or chamber through the vent opening 12. By reference to Figs. 7 and S of the drawings it will be observed that the lower end of the tube 21 is slightly tapered so that the same may fit snugly within the tapered opening 11 when the filler is employed in introducing ink into the pen.

In that form of the invention shown in Fig. 5 of the drawings the lower or marking edge of the pen is indicated by the numeral 10 and in this form of the invention the body of the pen is divided interiorly into three ink compartments, one indicated by 1 the numeral 9 another by the numeral 9 and the third by the numeral 9, the marking edge 10 being interrupted at intervals by notches cut therein and indicated by the numerals 1 1, 1 121 1, and 14. It will. be observed by reference to the said Fig. 5 that ink of the colorcontained within the comneeaymi supplied with ink of another color from the ink compartment 9 and these colors being blended. It will also be observed that ink will be supplied to that portion of the mark ing edge between the notches 145 and 14 from the compartment 9 and to the said marking edge between the notches 1l and 14 from the ink compartment 9. Also ink will be supplied from the compartment 9 to the portion of the marking edge at the left of the notch 14. Thus, in the specific instance illustrated in this figure, when the pen is drawn over the paper to be marked there will be marked upon the paper a relatively broad line of the color of the ink in the compartment 9, a relatively broad line of the blended colors of the inks contained in the compartments 9 and 9", a slightly narrower line of ink of the color contained in the compartment 9 a similar line of ink of a color of the ink contained in the compartment 9 and finally a narrower line of ink of the color contained in the compartment 9. This figure, however, is to be taken only as illustrative of one of the many arrangements which may be provided, depending upon the results desired to be obtained.

Having thus described the invention, what is claimed as'neW is:

1. In a marking device of the, class described, a reservoir divided into a plurality of ink compartments and provided with ink ducts communicating with the interior of the compartments and with the marking edge of the reservoir, the said marking edge being divided into a plurality of marking lengths, one of said lengths containing ducts leading from a plurality of said ink compartments.
